Lopez failed to appear in court after being charged with third-degree sexual abuse.

Authorities said Lopez is also possibly in violation of the protective order, but despite Karina's age, he most likely won't be charged with kidnapping.

"There's a difference between not wanting to be found or not wanting to be home and actually being abducted," Halifax said.

Investigators said evidence suggested Karina chose to go with Lopez. Halifax said there were two reasons an Amber alert won't be issued for her.

"First of all, they have to be abducted. We don't believe this is an abduction whatsoever," Halifax said. "Also, it has to be a belief or concern of great bodily harm, serious injury or death, and this doesn't meet that criteria."

Karina is a student at Meredith Middle School, and Lopez attended Hoover High School.
